OAR-LOCK.

Specification of Letters Patent.

Patented July 6, 1915.

Application filed February 25, 1914, Serial No. 820,938. Renewed May 17, 1915. Serial No. 28,773.

To all whom it may concern:

Be it known that LCHAnLns B. MALGHOW, a citizen of the United States, residing at Warner, in the county of Merrimackand State of New Hampshire, have invented certain new and useful Improvements n Oar-Locks, of which the following is a specification.

This invention relates to an oar lock, and the principal object of the invention 1s to provide an oar lock having a closure which will prevent the oar from slipping out of the oar look while rowing.

Another object of the invention is to provide an improved type of latch for releasably holding the locking link in a closed position.

Another object of the invention is to so construct the link and one of the arms of the oar lock that the end of the arm may fit into the pocket of the link in which the latch is pivotally mounted when the link 1s in the closed position.

Figure 1 is a View showing the oar lock in the closed position with the end portions of the closure shown broken away; Fig. 2 is a view showing the oar lock in elevation with the closure open; Fig. 3 is a sectional view taken along the line 22 of rig. 2.

The oar lock 10 is provided with the usual stem 11 and is substantially U-shaped to provide the arms 12 and 13. The arm 13 which is shorter than the arm 12 has its upper end formed into an eye 14 with which the closure bar or link 15 is pivotally connected by means of the pivot pin 16. The opposite arm 12 has its upper end portion 17 carried inwardly with its end 18 reduced so that the upper end of the arm 12 may fit the socket 19 formed in the free end of the bar 15. The face 20 of the arm 12 is flattened as shown in Fig. 2 and leads from the lower end of a notch 21 formed in the upper end portion of the arm. In order to releasably secure the bar 15 there has been provided a latch 22 which has its inner face cut to conform to the contour of the arm 12. From the'inner face of the latch there extends a tooth 23 positioned to extend into the notch 21 and prevent the bar 15 from moving upwardly when the latch is in the lowered position. In order to permit the latch to be easily raised a finger hold 21: has been provided so that the latch may be swung outwardly and permit the bar to be moved from the position shown in Fig. 1 to the position shown in Fig. 2. When this oar lock is in use, the oar is placed in the lock and the bar is moved to the closed position with the reduced end 18 extending into the pocket 19 between the pivot end of the latch 22' and the inner end of the-pocket. The latch of its own weight remains in the position shown in Fig. 1 and when in this position it will be impossible for the bar 15 to move upwardly a su-fficient distance to release the oar since the tooth 23 fits into the notch 21' and limits the upper movement. When it is desired to release the oars, the latch can be easily swung outwardly by means of the finger hold 24, and the bar can then be raised to bend the lock and permit the oar to be removed. This lock is therefore provided with a closure which is releasably held in a locked position; and which will prevent the oars from slipping out of the oar locks while rowing.

What is claimed is:

1. An oar lock having one arm provided with a notch, a closure bar pivoted to the other arm of said lock and having its free end portion provided with a pocket in which the free end of the first of said arms fits, and a latch pivotally mounted in the pocket of said bar and provided with a tooth extending into said notch whereby said bar will be held in a closed position with the end of said first-mentioned arm extending into said pocket between the pivot end of said latch and the inner end of said pocket.

2. An car look, a closure bar hinged to one of the arms of said oar lock and provided with a pocket in its free end and a latch pivotally mounted in said pocket and releasably engaging the second arm of said oar lock to hold said bar in a closed position with the free end of the said last-mentioned arm of said oar lock extending into the pocket into engagement with the pivot end of said latch and the inner end of the pocket.

3. An oar lock having one end provided with a notch, a closure bar carried by the other of said arms and extending to inclose the upper end of said first-mentioned arm, and a latch pivotally connected with the free end of said closure bar and provided with a tooth extending into the notch of said first mentioned arm, said latch being normally held in a position to hold said locked positionwith the free end ofisaid second-mentioned arm extending between said securing means and the end of said closure.

5. An oar lock having one arm terminating in an eye, the other arm having its free end portion carried inwardly and terminating in a reduced end and being provided with a notch and having its outer face flattened between said notch, a closure bar pivotally connected with the eye of said first-mentioned arm and having its free end portion provided with a pocket, and a latch v pivotally mounted in the outer end portion of said pocket and having its inner face conforming to the contour of the outer'face of said second-mentioned arm and provided with a tooth extending into said notch whereby said bar will be releasably held in engagement with said second-mentioned arm with the reduced end of the arm extending into the pocket between the pivot Copies of this patent may be obtained for end of said latch and the inner end of said pocket.

6. An oar lock, a closure movably connected with one of the arms of said oar lock and having its free end portion provided with a pocket, a latch having one end portion mounted in the outer end portion of said pocket, the other arm of said oar lock fitting into the inner end portion of said pocket and engaging the inner end portion of said latch to hold the same in a position to engage the second mentioned arm of the oar lock and prevent accidental releasing ofsaid closure.

7. An oar lock, a closure bar movably connected with one of the arms of said oar lock and having the free end portion provided with a pocket, a latch having one end mo'lunted in the outer end portion of said pocket and releasably engaging the second arm of said oar lock, and the free end of the second arm of the oar lock fitting into said pocket between said latch and the inner end of the pocket.
